BIGGERT, JR., 0F GRAFTON, PENNSYLVANIA, ASSIGNQB TO- UNITED EN- GINEERING & FOUNDRY COMPANY, OF PITTSBURGH, PENNSYLVANIA, A CORPORA- TION OF PENNSYLVANIA TRANSFERRING DEVICE Application filed January 4,

My invention pertains to transferring devices, and relates especially to devices for transferring articles, several at a time, to a receiving member and stacking them in tiers thereon. One useful application of my invention is in the piling of billets or the like, for instance as they emerge on the run-out table of a rolling mill.

It is one object of my invention to provide a device for transferring articles several at a time which will be of a simple, economical and rugged construction, easily manipulated, and certain and rapid in its operation. Another object is to provide such a transfer surface to and upon which the articles are to be transferred, whereby successive transferring operations result in the stacking of such articles in tiers. Other objects of the invention will appear from the following specification and claims.

By way of example, a material transferring device,'taking, in this instance, the

- form' of a. billet piler,constructed in accordance with my invention is described in the following specification and shown in the accompanying drawings. However, I wish it understood that the invention may be embodied in other constructions and a plied in other ways without exceeding t e scope thereof as defined in the appended claims.

In the drawings, Fig. 1 is an end elevation of the billet piler, and Fig. 2 is a fragmentary view showing one end thereof in plan. Referring now to such drawings, indicates the rolls of the run-out table of a rolling mill, upon which billets emerge one at a time, in the direction indicated by the arrows shown in Fig. 2, and are brought to rest, for instance by endwise engagement against a suitable stop or the like. Between the rolls 10, and slightly below the level of the same, are disposed horizontal aprons 11, and these aprons connect with. inclined skids 12.

1630. swarm). 418,505. Through each of the skids extends an upper stop 13 and a lower stop '14, the lower stop being spaced from the upper stop by a distance which is at least as great as the widest pile that will be required to be made. The

series of upper stops 13 are connected to cranks 15 on a shaft 16, and the lower stops are connected to cranks 17 on a shaft 18. The shafts 16 and 18 are operated by suitable power means which are manually controlled so that either the series of, stops 13 or theseries of stops 14 can be depressed at will. A pushing device 19 of anydesired construction is provided for pushing the billets off the rolls 10 and onto the upper parts of the skids 12, whereupon the billets slide down such skids and come to rest against the upper stops 13. When a suflicient number of billets have arrived against the upper stops 13 to make up a layer as wide as the desired width of the pile, the operator actuates the shaft 16 to depress the stops 13, whereupon the batch of billets slides further down the skids 12 and comes to rest against the lower stops 14, ready to be taken away by. the transfer spoons of the piler. The piler table comprises a series of rolls which are normally stationary, suitable means being provided for rotating them when it is desired to discharge the completed guides22, these being adjustable laterally of the rolls 20, as, for instance, by securing them to the aprons by means of screws or the like passing through slots in the side guides. The side guides are beveled at their leading ends,

as indicated at 23, so as to avoid the presence of corners in the path of any billet ends which may project laterally somewhat from the pile,

as, for example, when short billets are being.

piled. Secured to the supporting frame for layer on top of the other, from the skids 12 to the piler rolls 20. v

The framework of the machine is provided with a plurality of rails 26 upon which are adapted to run the wheels 27 of a large carriage 28 which extends substantially the entire length of the machine. The carriage is adapted to be given a complete backward and 1 return reciprocation, when desired, by means of a plurality of connecting rods 29, one of which is shown at the right of Fig. 2, these connecting rods being pivoted between the carriage and the crank pins of cranks 30 on a shaft 31. When it is desired to transfer a layer of billets from the skids 12 to the piler rolls 20, the operator, by manipulating a limit switch'or the like, causes the shaft 31 to turn through one revolution, which causes the carriage 28 to roll backward on the rails 26 and then return'to its original position.

Pivoted upon the carriage '28, one'opposite each skid 12, and arranged so as to extend betweeneach pair of'side guides-22, 25, are a series of spoons 32, each of which is provided' with a blade 33 disposed and arranged to enter a notch in the corresponding skid. The spoons are formed with ledges 34 against which the billets are adapted to strike. Each spoon is further formed with a rearwardly.

extending counterweight arm 35 of such mass as to overbalancethe spoon when the latter is empty but to be overbalanced by the spoon when the latter has upon itthe smallest weight which it will be required to carry. An

f adjustable abutment 'member 36 mounted on the carriage 28, is provided for engagement by the counterweight arm 35 of each spoon.

These abutment members are so adjusted that l whenthey are engaged by the counterweight arms the ends ofthe blades 33 of the spoons will lie in the notches of the skids 12 and be on substantially the same level as such skids. 1 Secured to' the standards 24 are cam members 37 having horizontal portions 38 and upwardly and rearwardly inclined portions- 39. These cam members are adapted to beengaged by rolls 40 which extend laterally from the counter-weight arms 35, the horizontal portions 37 being so disposed as to maintain the spoons in their highest positions, in which the counterweight arms engage against the abutments 36, when the carriage 28 -is in its extreme forward position. Thus, when billets are supplied to the spoons, the latter are revented from immediately. descending, bec use of the weight of such billets, by the engagement of the rolls 40 against the horizontal portions 38 of the cam members. When, however, the carriage 28 is moved rearwardly, the rolls 40 run up the inclined portions 29, thereby allowing the spoons to swing gradually downward.

er 19, as the billets emerge upon the run-" out table, until the number of billets which is desired to make up one layer of the )ile, say six billets, have accumulated on the skids 12 against the lower stops '14. Thereupon the bperator raises the upper stops 13, to allow the billets thereafter to accumulate against them, andigive time for the transfer from the skids 12 to the piler rolls 20 to be made. To effect the transfer, the operator first depresses the lower stops 14,. whereupon the batch of; billets slides down from the skids onto the blades 33 of the spoons 32, coming to rest againstthe abutments 34. The operator then actuates a limit switch or thelike to cause the crank shaft 31 to make a complete revolution. the batch of billets arriving upon the spoons 32, the latter are prevented from swinging down, under the weight of the billets,

- which overbalances the weight of the coun- Upon rolls 40 with the horizontal portions 38 of the cam members 37. As, however, the carriage 28 moves to the left '(Fig. 1) the rolls 40 r1de up the inclined portions 39 of the cam members, allowing the spoons to swing gradually v down about their pivots, the inclined portions 39 of the cam members being so disposed that the billets carried by the spoons will not collide with the side guides 22. The billets will, however, engage the side guides 25 during the latter part of the trans er the only result, I however, being that the billets are held against further transverse movement, the

blades 33 of the spoons sliding transversely of the machine beneath them. By the time the spoons have reached the position indicated in dotted lines in Fig. 1, which will occur when the cranks 30 have made about a one-fourth revolution, the ends of the spoon blades 33 will have come close to, or in engagement with, the aprons 21. During the remainder of the-movement of the carriage 28 to the left the blades 33 of the spoons will be withdrawn from beneath the billets, which latter are retained by the engagement with the guides 25 and fall successively onto the piler rolls 20, to form the bottom layer of the pile. When-the ends of the blades 33 have passed from be neath the billets, the spoons, being" now empt and overbalanced by the counterweig t arms 35, will swing up again until the counterweight arms 35 strike the abutments 36, the position being the same as that shown in Fig. 1, except that the carriage 28, and the spoons supported thereby, are moved to the left. Upon the return of the carriage, the-v blades 33 of the spoons will enter the notches of the skids 12, ready to receive another batch v of billets. The next transferring operation level as is indicated by the broken line a,

- whereby said transfer member descends upon whereupon the piler rolls 20 are set in motion to discharge the whole pile of billets, which are in a neatly stacked condition. convenient for storage or for transfer to other apparatus in which it may be required that they be worked. a

The device of my invention provides a rapid and convenient means for collecting articles and transferring them in batches from one station to another. .Its further function of delivering the articles in the form ofa neat and compact pile is especially advantageous. For example, it effects a mate'- rial improvement in the handling of billets in rolling mill practice, where it has been common to deliver the billets in irregular heaps, requiring to be bundled before being seized by a crane, to be rearranged before being stacked in a storage pile, etc.
